' To all Iwhom, t may concern.'

Be it known that I', HENRY C. Osonn, a`A citizen of the United States,residing at Cleveland, inthe county. of Cuyahoga and State of Ohio, haveinvented a. certain new and useful Improvement in Printing Mechanisms,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings.

i The object of this invention isto provide in a simple and elicientform, a printing machine of a rotary type wherein the printing forni isplanular. By this combination, I obtain the continuous drive which ischaracteristic of rotary machines and also the ,ability to vuse ordinaryprinters type or flat electrotypes. I accomplish the desired result bymoving the platen in a circ-uit and swinging the type bedcorrespondingly, whereby the platen rolls over the bed in contact fromend to end and causesq the proper impression. This broad feature andother features contributing to the eiiciency and simplicity arecomprised within my invention, and are illustrated in the drawings andhereinafter more fully explained.

In the drawings Figure 1 is a. side elevation; Fig. 2 is a front viewpartly sectional; and Fig. 3 is a plan.

The frame of the machine, as shown, comprises a suitable base 10 fromwhich rise standards 11 and 12. Mounted above the base is the type bed14. This bed may consist of a tray, as shown, adapted to carry type 15locked therein in the usual manner to make a page form, as shown 1nFigs.

l and 2. The bed is pivoted by studslG,

in suitable ears 17 constituting a portion of the frame. |The axis ofthese studs alines with the face of the type.

Journaled in the standards 11 and 12 is a shaft 20, -on which arerigidly mounted aims 21 and 22. These arms carry near one end the rotaryplaten 24 and near the other the corresponding ink roller 25. ln theupper part of the macliineis a suitable inking disk 26 adapted to carryink on its under face. rI'he shaft 20 provided with a. crank 27, andwhen this crank is driven, the two rollers travel through a circuit andin doing so the inking roller 25 takes ink from the disk 2G and app-liesit to the type and thereafter the platen roller impresses paper laid on.the form onto the same. Both the inking disk and the type bed swing tocause proper contact of the rollers andv means are provided to preventthe platen roller being inked by the disk. The mechanisms forcontrolling these operations will now be described.

Depending from t-he type bed .14 is an ear 30 to which is secured aspring 31, the other end of which is anchored to the 'base as at 32. Theeifect of this spring is to give the type bed a tendency to assume aninclined position shown by the dotted lines in Fig. 1, being adjusted bythe stop screw 34y mounted in the frame. lThis inclined position of thebed is such that as the-platen roller comes downwardly toward the bed,before it engages the type.I rolls 35 on the arms 21 and 22 passunder'the ribs 38 on the side of the type bed. The under sides of these.ribs are so formed (in a curve which approximates a straight line, asshown) that as the rollers travel along under them, the face cfthecontacting line of type is maintained thereby at-aconstant dist-ancefrom the platen axis. -This action causes the platen and the inkingroller to vmaintain the desired contact with the typein the bed. As soonas the rolls have cleared the ribs 38, the type bed swings back intoposition shown in dotted lines in Fig. 1.

The inkipg disk is mounted by means of a swivel stud .40 in the rockingframe 41 which is pivotally mounted on studs 42 in ears 43 dependingfrom a cross bar 44. This cross bar is supported by means of rods -46 Ivertically slidable in ears 47 and 48 on the standards 11 and 12; thecross bar is pressed upwardly sufficiently to counterbalance its weight,by springs 49, and cams 50.011 the shaft 20 operated at the proper timemove the crossbar up or down.l The .cams are shown as disks havinggrooves 51 in which 'take contact rollers 52 on the lower ends `of therods 46.

The v'disk 26 is normally held in inclined position approximatelyparallel with the bed 14 by the spring 55, which is anchored at itsupper endto the cross bar 44 and at its lower end to anarm 57 projectingfrom the swinging frame 41. A suitable stop screw 58 limits the movementofthe disk. In this position of the parts,v whenQthe inking rollerapproaches the disk the rolls 60 on the arms 21 and 22 engage the up'per edges of ribs 61, (similar 'to the ribs 38) on the sides of theswinging frame 41 and' this position,the .elevation of its lett hand-jportion causes the pawl 65 pivoted to the cross bar flt to click overthe next tooth of a series of ratchet teeth 66 arranged inta circleabout the upper face of the inking disk. the disk and the latter swingsback into position under the influence of the springl 55, t-hepawlanchoringthe engaged ratchet tooth causes the disk-to turn on itsswivel 40, Accordingly, :the disk is periodically fed to present the inkthereon diiterently to the inking roller giving a proper distribution,as will be well understood. While the inking'roller is traveling past'the disk 26, the rolls 52 are each in a concentric portion 71, of thecam groove 51, which has a comparatively small radius whereby the diskis held down to the position throughout this portion v ofthe travel ofthe'inking roller. After the inking roller is moved beyond the disk, theportion 72` of the-cam groove engages the roll 52 and elevates the crossbar 44, the frame il and-the inking` disk so that the platen 24 andtherolls 35 may 'pass idly beneath the same without contact therewith,-thisidle passage being while the concentric portion 78 of larger radius ofthe cam groove is coperative with the roll 52. After the platen hasmoved past the inking disk thedecreasing portion 74C of the cam groovebrings the disk back to position for engagement.

ln order that the inkin'g roller may properly take its ink and Vink theform and in order that the platen roller may properly impress the form,it is desirable that these rollers be positively rotated as they comeinto action. Accordingly, l provide the rollers 24 and 25 with pinions77 and 78A rigid therewith which constantly mesh with an internal gear79 carried by suitable standards 18 and 19 rising from the base. Thisgearing causes the rollers Vto turn on their axis as they travel.

in the operation of my ,machine` the type form is made up and locked inthe bed in mrthe usual manner and the ink is supplied to the disk by anink knife or otherwise in the usual way, and by means ot the crank 27"',the trame carryingthe rollers is rotated.

litter the inking roller has inked and cleared Y the type bed and beiorethe platen roller en ages it.r a sheet of paper is laid on the which itat this time occupies the position shown in dotted lines in Fig. l.Owing to the open space above the type bed when rlhen when the-inkingroller clears inaaeor the two rollers are approximately in ahorizontalplane over the shaft 2O there isplenty of room and time forsupplying the paper. kby hand, even though the machine be driven withcomparative rapidity. 'A

lt is to be understood also that numerous adjustments for the variousparts to cause and maint-ain the proper present-ation of the 'rollersandfothe'r coperating parts will be supplied by the skilled mechanic inconstruct-ing the machine shown, and are.

omitted from the illustration tor the sake of simplicity.'
